SAN ANTONIO – The Bexar County Sheriff’s Office has released the names of three people who were arrested Wednesday night after a raid related to illegal gambling. A team of investigators descended on a home in the 300 block of East Mayfield that they believe was the site of the gambling operation and more. The sheriff said the raid came about through a joint investigation, initiated by a tip his office had received. “I can certainly see where the neighbors would not want this sort of operation going on in what’s really a nice quiet little neighborhood,” he said. Investigators seized more than $4,400 in cash, the motherboards from 18 gambling machines and a stolen car.
